Abstract

Dispositifs et procédés déviant le flux sanguin d'un premier vaisseau vers un second vaisseau et maintenant le flux sanguin dans le premier vaisseau. Le dispositif comprend un premier segment et un second segment. Le premier segment est configuré pour s'ancrer dans le premier vaisseau. Le premier segment comprend une fenêtre pour permettre au sang de s'écouler dans le premier segment, à travers la fenêtre, et de manière distale dans le premier vaisseau. Le second segment est configuré pour s'ancrer dans le second vaisseau. Le second segment est configuré pour permettre au sang de s'écouler dans le premier segment, à travers le second segment, et dans le second vaisseau.
